It's an Asian character. Before the Nazis bastardized it, it was originally meant for "good luck". No one should shy away from using it just because some other group stole it and created a negative image out of it.

Which, in my experience, is very easy to pull off because of how Armor Emblem benefits greatly from being in close proximity of each other. I'm using a Gronnblade/Wary Fighter Henry that truly is a weapon of mass destruction. Who needs to hit twice when you're sitting at 80 attack value after hone/fort and +4 from goad buffs?
